assign-symbols NPM version

Assign the enumerable es6 Symbol properties from an object (or objects) to the first object passed on the arguments. Can be used as a supplement to other extend, assign or merge methods as a polyfill for the Symbols part of the es6 Object.assign method.

From the Mozilla Developer docs for Symbol:

A symbol is a unique and immutable data type and may be used as an identifier for object properties. The symbol object is an implicit object wrapper for the symbol primitive data type.
